Hardware Design and Core Features
The Cisco Catalyst C9300L-24T-4G-E is a 24-port Gigabit Ethernet switch optimized for edge deployments where PoE isn’t required but scalability and uplink flexibility are critical. The “24T” denotes 24x 10/100/1000BASE-T ports, while “4G” refers to 4x 1G SFP uplinks for fiber or copper aggregation. Key specifications include:
- Fanless operation, making it ideal for noise-sensitive environments like libraries or open-plan offices.
- Cisco StackWise-160 support, enabling up to 4 switches to stack with 160 Gbps throughput.
- Energy Efficient Ethernet (EEE), reducing power consumption by up to 70% during idle periods.
Addressing Cost and Scalability Trade-Offs
A common question from IT managers is: “Does the lack of PoE limit its use cases?” For networks already utilizing PoE injectors or separate PoE switches, the C9300L-24T-4G-E’s lower upfront cost (up to 25% cheaper than PoE models) becomes a strategic advantage. For example, a manufacturing floor using hardwired PLCs or non-PoE sensors can allocate savings toward security or uplink upgrades.
Another concern—“Can it integrate into mixed-stack environments?”—is resolved via StackWise-160 compatibility with other Catalyst 9300L models. This allows hybrid stacks combining PoE and non-PoE switches while maintaining unified management through Cisco DNA Center.
Licensing and Operational Efficiency
The “E” suffix includes Cisco DNA Essentials for Lifecycle Management, covering zero-touch provisioning, device hardening, and basic automation. Unlike subscription-based licensing on higher-tier Catalyst switches, the C9300L-24T-4G-E’s perpetual license minimizes recurring costs—a critical factor for public sector or education budgets.
Deployment Scenarios: Where It Delivers Value
This switch excels in:
- Branch offices requiring reliable uplinks for VoIP gateways or SD-WAN appliances.
- Industrial control systems (ICS) with legacy non-PoE equipment.
- Retail back-of-house networks connecting inventory databases and POS terminals.

Practical Takeaways
Deploying this model in a municipal library network underscored its silent operation and effortless integration with existing fiber backbones. While competitors like Juniper EX2300 offer similar port density, the C9300L-24T-4G-E’s StackWise simplicity and DNA Essentials inclusion eliminated the need for third-party tools—a decisive factor for teams managing hybrid infrastructures with limited resources. For organizations prioritizing CapEx reduction without sacrificing future-readiness, this switch proves that sometimes, less (PoE) truly is more.
